I refuse to buy new and my current car cost me $15kAUD. Which is 10KUSD (ignoring supply chain issues for a while). My previous car was an older generation of the same model and lasted over a decade. My current car should too. And upkeep is fairly cheap all things considered.
20K isn’t economy. Half that and make sure the car still runs for over a decade with reasonable maintenance costs.
"Now include the AUD1.80/L fuel costs into the life of that car."
While remembering, of course, to include AUD0.30-0.60/kwh for charging the EV (or AUD$6-$12/100km for a typical EV).
where by cheaper you mean slightly more expensive if you compare to public charging stations that are the vast minority of charged miles, and 9x more expensive than charging at home.
